PATENT WORTHY C. HARPER, 0F CALDWELL, OHO.

PIN FASTENER.

Application filed July 5, 1922.

To all whom 'it may concern.'

Be it known that I, WORTHY C. HARrnR, a citizen of the United States of America, residing at Caldwell, in the county of Noble and State of Ohio, have invented certain new and useful Improvements in Pin Fasteners, of which the following is a specification.

My invention relates to pin-fasteners and has for its object:

First, to construct a pin in which the tongue thereof is insulated from the flesh of the person using it on garments worn next to the flesh; second, to provide triple holding friction surfaces on the cloth in which it is used; third, to make the pin tongue and side bars so that the tension on the clothis on the pin and side bars and not on the pin entrance hold and pin outlet hold; fourth, to construct a pin having great efficiency in holding; and fifth, to construct the pin in such a manner that the point of the tongue will not catch in the garments of the wearer,

l and will not tear the flesh ofthe person using the pin. I

With these and other objects in view, one embodiment of my invention is shown in the accompanying drawing in which:

Figure 1 is a plan view of my pin inserted in layers of cloth;

Figure 2 is a section on lines 2--2 of Figure l;

Figure 8 is a side elevation with the tongue swung to an angle with the side bars;

Figure 4; is a section on line 4-4 looking in the direction of the arrow; and

Figure 5 is a section on lines 5 5.

My pin fastener, which may be made of .any suitable material, comprises a tongue l and side bars 2 and 3, the side bars being made of a single piece of metal. The tongue l is fastened to the side bars in any suitable manner` as by bending it around the side bars as shown at 4L, enabling the tongue to swing freely on the side bars as a pivot. The side bar 2 is curved forming substantially a semicircle 5. The bar 3 is bent at a right. anule at 6 to the plane of the bar and the end is curved upward forming a loop to t loosely around the side bar 2.

My pin fastener is shown conventionally as applied to two layers of cloth 8 and 9. It may of course be applied to any desired number of layers of cloth or other material.

lt will be noted as shown by Figure 5 that the point of the pin l is in line with the Serial No. 572,763.

curved sides of the bar 5, thus preventing the point of the pin from scratching the flesh, and also preventing it from catching the garments of the wearer of the pin.

rIhe friction of the cloth on the pin will be at the points indicated by 10, 11, and l2. This construction prevents the cloth from being torn at the points of entrance of the pin and eXit of the pin, 13 and 14 respectively. llt will be noted as clearly disclosed in Figures 2 and 5 that the cloth which passes between the tongue and side bars is raised above the pin tongue. The distance the cloth is raised by the pin where it is inserted is approximately twice the thickness of the material of which the bars and tongue are made.

What l claim and desire to protect by Letters Patent is:

l. A pin fastener comprising a tongue and side bars, said side bars being made of a single piece of material, said tongue being pivoted at one end of said side bars, one end of said side bars being curved substantially semicircular whereby the point of the tongue is protected and the other end of the side bar having a part of the end thereof bent at a right angle to the plane of the bar and with the eXtreme end curved upward to form a loop to encircle the other side bar.

2. A pin fastener comprising a tongue to be inserted in material and side bars, said tongue being movably mounted at one end of said bars said tongue for substantially the length adapted to be inserted in material, being raised above said side bars, whereby said tongue is prevented from coming in contact with that upon which said material rests.

3. A pin fastener comprising a tongue and side bars said tongue being movably mount ed at one end of said bars in combination with material passed over said tongue and under said bars whereby triple friction on said tongue and side bars is produced.

4i. A pin fastener comprising a tongue and side bars, said tongue being movably mounted at one end of said bars said tongue being raised above the plane of said side bars, in combination with material passed over said tongue and under said side bars whereby triple friction on said tongue and side bars is produced.

5. In a pin fastener, side bars made of a single piece of material, a tongue pivoted at lOl) one end of said bars, one encl of the piece of material constituting the side bars bent at an angle to the side bars whereby a rest is formed for the end of the pivotecl pin.

6. In a, pin fast-enel', side bars made of a Single piece of material, a tongue pivotecl at one end of said bars, one end of the pieceof material constituting the side bars bent at an angle to the side bars whereby a rest is formed for the end of the pivotecl pin, and l0 said end of said piece of material bent at an angle being attached toeJ side bar.

In testimony whereof I aiiix my signature.
